What is titanium alloy anodizing technology？

Titanium alloy is a metal material with high strength, light weight, corrosion resistance, etc. It is commonly used in aerospace, medical devices, chemical industry and other fields. In order to further improve the surface performance of titanium alloy, anodizing technology is usually used for surface treatment.

Titanium alloy anodizing is a surface treatment technology, a method of using electrochemical reaction to form an oxide film on the metal surface, which can improve the hardness, abrasion resistance, corrosion resistance and other properties of the metal surface. After anodizing treatment on the surface of titanium alloy, a dense oxide film can be formed, and its thickness and color can be adjusted by controlling the oxidation time and voltage. Usually, the surface of titanium alloy after anodic oxidation shows different colors such as dark gray, brown, golden yellow, etc. These color changes are related to the thickness and composition of the oxide film.

The film has high hardness and corrosion resistance, which can effectively protect the surface of titanium alloy from the erosion and damage of the external environment. Its main features include:

1. High hardness: The hardness of the oxide film on the surface of titanium alloy after anodizing can reach 600-1000HV, several times higher than that of the original titanium alloy surface.

2. Corrosion resistance: The oxide film on the surface of titanium alloy after anodizing can effectively prevent corrosion and oxidation of the titanium alloy, improving its corrosion resistance.

3. Various colors: The oxide film on the surface of titanium alloy after anodizing can present different colors, such as golden yellow, dark gray, brown, etc., with good decorative properties.

4. Environmental protection: Anodizing is a pollution-free surface treatment technology that does not produce harmful substances and is environmentally friendly.

The process of titanium alloy anodizing generally includes: cleaning, decreasing, pickling, anodizing, dyeing, sealing and other steps. Among them, anodizing is the key step, which needs to realize the formation of oxide film by controlling parameters such as voltage, current and oxidation time.

In the field of bottles, titanium alloy anodizing technology can be applied to the surface treatment of insulation bottles, coffee pots and other products. Through anodizing treatment, the hardness and corrosion resistance of the product surface can be improved, and the appearance of the product can be improved to make it more decorative.

It should be noted that although titanium alloy anodizing technology has many advantages, there are also some limitations. For example, the oxide film after anodizing has a certain brittleness and is susceptible to mechanical damage, so it needs to be protected in the process of use. In addition, the cost of anodizing is relatively high, which requires professional equipment and technology investment.

In conclusion, titanium alloy anodizing is an effective surface treatment technology that can improve the surface performance and service life of titanium alloy, as well as improve its appearance. In the field of bottles, the application of this technology can give higher value and competitiveness to the products.
